V l lClaim.

This invention relates itostools and more, par- ,ticularly to astool.thatiscollapsible and adjustable.

An object of the invention is to provide a stool that, when in use, can be adjusted to various heights and when not in use, can be collapsed into a compact assembly for the easy storage thereof.

A stool constructed in accordance with the invention can be easily transported to be used for camping, picnics, fairs or similar occasions where a stool is desirable.

With the above and other objects and advantages in view, the invention consists of the novel details of construction, arrangement and combination of parts more fully hereinafter described, claimed and illustrated in the accompanying drawing in which;

Figure 1 is an elevational view, partly in section on the approximate line II of Figure 2 of an embodiment of the invention;

Figure 2 is a top plan View of the stool approximately on the line 22 of Figure 1;

Figure 3 is a sectional view on the line 3-3 of Figure 1;

Figure 4 is a fragmentary sectional view on the line 4-4 of Figure 5 and Figure 5 is a sectional view on the line 55 of Figure 1.

Referring more in detail to the drawing, the stool constructed in accordance with the invention is generally designated by the numeral III. The stool comprises a saddle seat II which may be made of wood or a suitable substitute therefor, to the bottom of which is secured by fasteners I2, a metal disc I3. The disc I3, at its center, is provided with an internally threaded enlargement I4 to engage the upper threaded end I5 of the adjusting screw I6.

The screw It passes loosely through the central opening I! of the blockIB which like the left seat II may be made of wood or a suitable substitute therefore. Adjustment of the seat II with relation to the block I8 is provided by means of the upper and lower plates I9 and 20, which are secured to the block I8 by the fasteners 2|. The plates are each provided with a central opening 22 which are tapped to cooperate with the threads on the screw I 5. Thus the distance intermediate the seat I I and block It may be adjusted by rotation of the seat II.

The block I8 is provided with downwardly and outwardly inclined sockets 23 which are arranged in the block at an angular relation to the vertical axis of the block. Similar shaped openings 24 are provided in the lower plate 2Il-sothat the upper endof thet-ubularsection 25 of the telescopic legs 25 may be inserted into the sockets in tripod fashion.

The smaller tubular section 2'! of the legs 26 is -slidable in the section '25 in the conventional manner, and on the lower end is provided with the non-slip rubber tip 28.

Adjustable relation of the sections 25 and 21, one to the other, is obtained through the medium of relatively spaced openings 29 in the section 21 which are selectively engaged by the latch lug 30 carried by the spring arm 3|. The spring arm 3| is secured by fasteners 32 to the section 25. A knob 33, on the lug 3U, outwardly of the arm 3| may be grasped by the fingers as shown in Figure 5, so that the lug can be removed from the openings in the section 21 for the adjustment of said sections with relation to each other. The lug 30, in its movement, plays through an opening 34 in the section 25.

The stool thus partly described is adjustable for height by lengthening or shortening the relative position of the sections of the legs or by rotation of the screw I6.

For the comfort of the occupant of the seat I I. a back rest assembly 35 is associated with the seat in the following manner.

A bracket 36 secured to the under surface of the seat I I by fasteners 31 is provided with a tubular enlargement 38 which loosely receives the bent tubular standard 39. The standard 39, at its upper end, carries a bolt 40 which passes through the curved back rest 4| securing the back rest to the standard in fixed relation thereto by the winged nut 42.

A winged screw 43 threadably mounted in the enlargement 38 engages an opening 44 in the opposite end of the standard 39 to retain the back rest in fixed elevated relation to the seat II.

It will be obvious that by rotating the seat I I, or lengthening or shortening the legs 26 in the manner previously described, the height of the stool may be adjusted according to the desires of the occupant.

The stool is completely collapsible for storage in the following manner.

The back rest 4| is removed from the standard by removal of the nut 42. Removal of the screw 43 permits the standard to be removed from the enlargement 38.

The screw I6 is unthreaded from the plates I9 and 20 and from the enlargement Id. The sections 25 are removable from their sockets 23 in the block I 8 and the sections 2! can be disengaged from the sections 25 by disengaging the lug 30 from the opening 29.

Thus completely dismantled, the parts of the stool can be easily packed for use at any desired location or stored, as the occasion requires.

There has thus been provided a stool that is collapsible, and adjustable, easily assembled or collapsed and once assembled, will effectively perform any task for which it is designed.

It is believed that from the foregoing description, the construction, manner of adjustment and the manner of collapsing the stool will be apparent to those skilled in the art. It is also to be understood that changes in the minor details of construction, arrangement and combination of parts may be resorted to, provided they fall within the spirit of the invention and the scope of the appended claim.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:

plates secured respectively to the upper and lower sides of the block, screw threaded openings in the upper and lower plates concentric with the opening in the block and adapted to operatively receive said screw, and said block and said lower plate having openings inclining downwardly and outwardly with respect to the screw and adapted to removably receive the upper end portion of the legs.
